After the shutdown, that apparently didn't show nothing abnormal, one of my larger lvm, with the home's users reported an error. At a fist seen one disk seems to be not mounted becuase the vg/pv did not start. After a restore of my lvm configuration, that vg/lv started correctly. But many errors comes out : Sep 7 20:14:26 giove kernel: for (lvm(58,1)) Sep 7 20:14:26 giove kernel: lvm(58,1):Using r5 hash to sort names Sep 7 20:14:26 giove kernel: is_tree_node: node level 0 does not match to the expected one 2 Sep 7 20:14:26 giove kernel: lvm(58,1):vs-5150: search_by_key: invalid format found in block 12022576. Fsck? Sep 7 20:14:26 giove kernel: lvm(58,1):vs-2140: finish_unfinished: search_by_key returned -2 And so on. The reiserfsck without option, did not solve anything. The disk was mountable, but a lot of damaged link insted of normal files were in many directory. THe last thing to test was --rebuild-tree, that solved the problems of the damaged files, but not like i thinked, it was created a lost+found dir with a lot of file, more than 30.000 and subdir. I do not understand what happens, with an old server, 2.2.X and reiserfs 3.5 without lvm, i switched of a lot of time with some partition of more than 100 g and NEVER a file was losted. I forgot to say that into the lost+found i have only file of the courier maildir, but some well know file, some avi's of 400mega, was completely lost!! Why this happens? Is the couple lvm-reiser less solid than reiser directly on a partition? Thanks for any info, and sorry for the bad english. Michele
